Clapham Retrofit

This 4-storey semi-detached Grade II listed Victorian townhouse has been eco-retrofitted to a high standard of airtightness and thermal performance. The 170-year old, solid brick building has been internally retrofitted with over 9 types of insulation material, each a bespoke solution to localised performance requirements respecting the historic significance of the existing fabric. The existing sash windows and doors have been upgraded through the installation of double-glazed secondary glazing. High performance insulation materials together with careful airtightness and thermal bridge detailing have resulted in a historic building that is both highly energy efficient and more comfortable to live in.

New Farmhouse

Passivhaus Trust Awards 2014 Winner - Bespoke Project Design Category - Kirsty Maguire Architects worked in collaboration with Hope Homes and Morgan Associates to design and build this farmhouse to the Passivhaus standard. Construction started in August of 2012, and the building was completed and certifed as a Passivhaus 12 months later. The house has a timber frame with I-joists, glulam beams and zinc cladding for the roof, a small wood burning stove, with hot water provided by an air source heat pump.

Hindolveston Housing

Passivhaus Trust Awards 2014 Finalist - Mole have worked with Broadland Housing to develop designs for 2 affordable housing developments of 2 and 3-bed houses in Norfolk, both are now complete and include four houses to Passivhaus standards. Materials draw on a locally sourced selection of clay pantiles, brick and naturally finished timber boards. Careful North/South orientation and solar shading makes best use of passive solar gain. In addition, a compact form, restriction of overall window size with predominantly south facing openings, high levels of insulation, heat recovery ventilation and extensive use of timber for primary structure, all combine to reduce energy loss.

Grove Cottage

Extension & Refurbishment of Victorian Townhouse using Passivhaus methodology and CarbonLite guidance. Certified to the Passivhaus Institute's new EnerPHit (refurbishment) Standard. [NEW:Passivhaus Trust awards shortlisted project - presentation available on these pages].PHPP certification is based on 20 C, rather than the 21 C the house was heated to during 2010/11. Forecasts are based on a 'typical year' rather than the 'actual' year being monitored. Measured data here is from 2005/06 (before) and 2009/10 (after). Measured room temperatures show an average of 21 degrees centigrade during the heating season. Please note the final air leakage as certified under EnerPHit was an N50 of 1.0 ACH. When adjusted for 2010 average monthly temps.& an internal temp. of 21 C, PHPP predicted a space heat demand of 36kWh/m2.a whereas 35kWh/m2.a was measured.

2050 Now! Achieving the standards for 2050, and the potential role for innovative heating solutions in thermally improved homes

The project will be improving four homes to different levels and exploring the performance of new heating solutions to achieve the optimum balance of energy performance vs. heating input for these different technologies. The three main innovative heating technologies in this project are Baxi's Ecogen domestic CHP (dCHP), Baxi's Ambiflo ASHP and Nuaire's Sunwarm (combined positive input ventilation, solar thermal heating and solar hot water). The dCHP units will be installed in relatively worse performing households and the ASHP units in well insulated houses to understand the level of performance needed from homes to create the right environment for these technologies to achieve significant carbon savings.

A2 Dominion- Northholt,

This typical semi-detatched property has poor orientation for exploiting solar gain and the residents will remain in their home during the works, making this a particularly hard to treat property. The rewards however are great, with approx 5.9 million semi detatched properties in England which could be treated similarly. We aim to deliver a highly cost effective and replicable solution, using innovative solutions such as the solar shed , blown underfloor insulation, cork external insulation and bio-foam loft insulation in a holistic design approach. The proposals have been detailed and specified with a strong emphasis on UK based expertise and technologies.

Planned occupancy : For the SAP and PHPP modelling an occupancy of 2.1 people has been assumed as per the TSB competition requirements. For the hot water assumptions for sizing the solar thermal system an occupancy of 3 people was assumed which we feel is a more realistic figure for a 3 bedroom house.

Addressing Energy Consumption and Climate Change Adaptation in non-South facing, post-Decent Homes properties.

The project property is an east-west facing, brick cavity construction, mid terrace house built in 1992. This type and era of dwelling correspond to approximately 100,000 similar social properties in England alone. We have developed a holistic strategy that will reduce the CO2 emissions of our proposed property by 80% whilst addressing how existing homes can adapt to climate change in the future. Our proposal is a combination of existing technologies used along side new innovative solutions to form a comprehensive strategy to reduce heating, hot water and electricity use. The underlying strategy is replicable across all terraced housing.

  • Airtightness : 6.76 m³/m².hr @ 50 Pascals

Planned occupancy : The current tenants have lived at the property for nearly 17 years. The presence of a long term, sitting tenant will help the team to collect valuable operating energy use data and demonstrate the impact of our behavioural change measures. It is proposed that the tenants will remain throughout phase 2. Close communication and considerate construction practices will help to avoid decanting the residents. We believe this is important to enhance the scalability of our proposals.
